The covalent attachment of a glycosyl residue to a substrate molecule. The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y, as carried out by individual cells. The modification of a protein by amino acid glucuronylation, the addition of a glucuronate group, the uronic acid derived from glucose. Any process that modulates the frequency, rate or extent of protein amino acid glycosylation. Protein amino acid glycosylation is the addition of a sugar unit to a protein amino acid, e.g. the addition of glycan chains to proteins. The glycosylation of peptidyl-amino acids through a phosphoester bond forming, for example, GlcNAc-alpha-1-P-Ser residues. The chemical reactions and pathways involving glycoproteins, any protein that contains covalently bound glycose (i.e. monosaccharide) residues other than as a moiety of nucleic acid; the glycose occurs most commonly as oligosaccharide or fairly small polysaccharide but occasionally as monosaccharide. A protein amino acid glycosylation process in which a sugar unit is added to a protein via a C atom. The chemical reactions and pathways resulting in the formation of glycoproteins, any protein that contains covalently bound glycose (i.e. monosaccharide) residues other than as a moiety of nucleic acid; the glycose occurs most commonly as oligosaccharide or fairly small polysaccharide but occasionally as monosaccharide. A protein amino acid glycosylation process in which a sugar unit is added to a protein via the hydroxyl group of peptidyl-serine, peptidyl-threonine, peptidyl-hydroxylysine, or peptidyl-hydroxyproline, or via the phenol group of peptidyl-tyrosine, forming an O-glycan. The addition of a galactose molecule to a protein amino acid. The chemical reactions and pathways resulting in the formation of a macromolecule, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass, carried out by individual cells. A protein amino acid glycosylation process in which a sugar unit is added to a free alpha-amino or alpha-carboxyl terminal of a peptide. Any process that activates or increases the frequency, rate or extent of the glycosylation of one or more amino acid residues within a protein. Protein amino acid glycosylation is the addition of a sugar unit to a protein amino acid, e.g. the addition of glycan chains to proteins. The chemical reactions and pathways by which individual cells transform chemical substances. Any process that stops, prevents or reduces the frequency, rate or extent of the glycosylation of one or more amino acid residues within a protein. Protein amino acid glycosylation is the addition of a sugar unit to a protein amino acid, e.g. the addition of glycan chains to proteins. The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule. The addition of a sugar unit to a protein amino acid in any compartment of the Golgi apparatus. The addition of a sugar unit to a protein amino acid at the surface of a cell. The addition of a sugar unit to a protein amino acid in the cytosol. The addition of a sugar unit to a protein amino acid in the endoplasmic reticulum. The addition of a mannose residue to a protein acceptor molecule. A protein amino acid glycosylation process in which a sugar unit is added to a protein via a sulfur atom of a peptidyl-amino-acid such as cysteine or methionine. The covalent alteration of one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule, resulting in a change in its properties. A protein modification process that results in the addition of a sugar unit to a protein amino acid, e.g. the addition of glycan chains to proteins. A protein amino acid glycosylation process in which a sugar unit is added to a protein via the N4 atom of peptidyl-asparagine, the omega-N of arginine, or the N1' atom peptidyl-tryptophan. The covalent attachment of a glycosyl residue to one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule. The chemical reactions and pathways involving a specific protein, rather than of proteins in general, occurring at the level of an individual cell. Includes protein modification. The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification).
